## Grid Graphics

### Description

General information about the grid graphics package.

### Details

Grid graphics provides an alternative to the standard R graphics. The user is able to define arbitrary rectangular regions (called viewports) on the graphics device and define a number of coordinate systems for each region. Drawing can be specified to occur in any viewport using any of the available coordinate systems.

Grid graphics and standard R graphics do not mix!

Type `library(help = grid)` to see a list of (public) Grid graphics functions.

    ## Diagram of a simple layout
    grid.show.layout(grid.layout(4,2,
                         heights=unit(rep(1, 4),
                                      c("lines", "lines", "lines", "null")),
                         widths=unit(c(1, 1), "inches")))
    ## Diagram of a sample viewport
    grid.show.viewport(viewport(x=0.6, y=0.6,
                                w=unit(1, "inches"), h=unit(1, "inches")))
    ## A flash plotting example
    grid.multipanel(vp=viewport(0.5, 0.5, 0.8, 0.8))
